Hi-
I just purchased a Lionel 6-34144 Scrap Yard. It’s well detailed and the animations are great. It comes woith “4 vent sections” with no indication in text or picture what to do with them. Any ideas?
Thanks,x2000
If there are no instructions or anything else showing how to use them try looking at the on-line catalog which covers this item and see if the photo there gives you any indication as to how it is used.
